Definitions
- the present invention generally relates to medical sensors and more particularly pertains to sensors that generate data indicative of a patient's movements or activity.
- Patients are routinely monitored with respect to certain parameters that may be affected by the patient's activity.
- the effect may be the result of a physiological change resulting from such activity, a variation in the sensor/patient interface or some alteration of the signal after its generation and during transmission to the related instrumentation. It may therefore be most beneficial to have a record of the patient's activity to assist in interpreting data collected with respect to the parameter of interest. "Motion artifacts" can thereby be quickly identified, as can the data that is generated during periods of activity and periods of inactivity.
- Motion transducers for monitoring patient activity typically employ piezo-film material which generates an electrical signal when mechanically disturbed.
- material has heretofore been incorporated in for example a bracelet from which electrical leads extend to instrumentation where the generated signals are processed and recorded or otherwise made available for analysis.
- the present invention provides a means for reducing the apparent complexity of the sensors and wiring array used in instrumenting a patient. More particularly, this is achieved by incorporating a motion transducer within a cable that interconnects any of a variety of sensors to instrumentation.
- An oximeter probe attached to the patient's finger necessarily has a cable extending therefrom that is typically routed along the hand and arm to the torso and on to the instrumentation.
- a substantially simplified visual appearance results.
- the cable is secured to the wrist with tape or elastic bands to ensure that the slightest movement of the wrist causes a signal to be generated.
- the present invention is adaptable to many other sensor combinations.
- the motion detector is incorporated in the cable interconnecting a primary sensor with the related instrumentation.
- the location of the piezo-film is selected to ensure its positioning adjacent to the body part the motion of which is of interest.
- FIG. 1 is semi-schematic representation showing the integrated sensor of the present invention.
- the present invention provides for the consolidation of an activity sensor with a primary medical sensor used to measure a particular medical parameter.
- the primary sensor is attached to the appropriate portion of a patient's anatomy, while a motion transducer is incorporated in the cable interconnecting the primary sensor with the related instrumentation. Information indicative of the patient's activity is thereby available for interpretation of the primary sensor data without the need to attach a separate sensor or route additional wiring.
- the FIGURE illustrates a motion transducer incorporated in a cable extending from an oximeter finger probe.
- oximeters are well known in the art, and are operative to project beams of light through the finger and measure the intensity of the transmitted radiation.
- the wavelength of one of the beams of light is selected so as to be absorbable only by oxygen carrying hemoglobin while the second beam of light is not absorbed thereby.
- the relative intensities of the two beams provide an indication of the oxygen saturation level.
- the signal is however easily affected by any movement of the probe relative to the finger as different blood vessels are thereby caused to come under scrutiny. In order to be able to distinguish a real change in blood oxygen from a motion artifact it is therefore necessary to monitor the patient's movements.
- the FIGURE shows a preferred embodiment of the present invention wherein the integrated system 12 includes an oximeter finger probe 14 that is interconnected via cable 16 to instrumentation 18 that amplifies, processes, displays or records the data.
- instrumentation 18 that amplifies, processes, displays or records the data.
- a section of piezo film 20 is wrapped about a section the cable.
- the piezo film 20 forms a cylindrical shape about a central axis of the cable 16.
- a preferred piezo film material is poly-vinylidine fluoride (PVDF).
- PVDF poly-vinylidine fluoride
- An outer sheath 22 covers the sensor 20 and wires 23 to provide a "single cable" appearance.
- the sheath may have a contrasting color or stenciling to demark the location of the sensor. It is preferred that the processing electronics for the motion transducer be incorporated in the same case that houses the oximeter electronics to further simplify the instrumentation.
- the oximeter finger probe 14 is clipped on to the patient's finger and the cable 16 is routed up along the arm to torso from where it connects to the instrumentation 18.
- the section of cable containing the motion transducer which is axially distant from the oximeter finger probe 14, is positioned over the patient's wrist and adhesive tape or elastic bands are used on either side of the transducer containing section to affix the cable to the patient. Any relative movement across the wrist causes that section of cable to move or flex to mechanically disturb the piezo film, which causes an electric signal to be generated that is transmitted to electronics 18 for processing.
- the activity sensor may be incorporated in any cable extending from the patient and consequently, integration with any number of medical sensors is possible. Additionally, any portion of the patient's body may be monitored for movement and any type of motion transducer may be used that is capable of being incorporated in the cabling. Accordingly, it is not intended that the invention be limited except by the appended claims.
